Academics and technologists are sounding the alarm about a growing crisis in scholarship as we know it: AI-generated citations of nonexistent papers that have infested real journals. Despite being fake, the sources are widely assumed to be authentic the more they appear in published literature.
AI Is Inventing Academic Papers That Don't Exist -- And They're Being Cited in Real Journals
Academic articles from authors using large language model are creating an ecosystem of fake research that threatens human knowledge itself.

Google Scholar attributes papers automatically to authors, a problem with homonyms when they do not clean up their profiles. It is also generous in matching citations. #RePEc requires authors to claim their papers and has stricter criteria for citation matching, thus does not inflate stats.#EconSky
Google Scholar’s citation errors skew h-index leaderboards
Thousands of mistakenly awarded citations left uncorrected highlight the perils of leaving profile curation to academics, say critics

Did you know that from tomorrow, Qualtrics is offering synthetic panels (AI-generated participants)?

Follow me down a rabbit hole I'm calling "doing science is tough and I'm so busy, can't we just make up participants?"
Text reads: About synthetic panels Recruiting the right participants for a study can be difficult. You may not get the exact demographics you need, and the shorter the deadline, the less sure you can be that everyone will answer on time. One possible solution can be to use synthetic panels. Synthetic panels are powered by a first party proprietary AI model developed here at Qualtrics. Our synthetic panel is trained on thousands of responses from a variety of demographic backgrounds in order to more accurately predict how certain populations would respond to a survey. Our synthetic panel is based on the United States General Population, and is only available in English. This panel comes with ready-made quotas and target breakouts in order to represent your chosen population and make it easy to launch your survey right away. Text reads: Question-writing best practices To get the most reliable and actionable results from synthetic audiences, consider these question-writing best practices: Ask forward-looking and attitudinal questions. Synthetic panels perform best with perceptions, preferences, and intent-based questions. For example, “How likely are you to try…?” Synthetic panels are less applicable for studies on past behaviors, detailed recall, brand recall, or awareness questions. For example, “When did you last visit…?” Text reads: Discussion The current study aimed to conduct a meta-analysis of the TPB when applied to health behaviours which addressed the limitations of previous reviews by including only prospective tests of behaviour, applying RE meta-analytic procedures, correcting correlations for sampling and measurement error, and hierarchically analysing the effect of behaviour type and sample and methodological moderators. Some 237 tests were identified which examined relations amongst model components. Overall the analysis indicated that the TPB could explain 19.3% of the variance in behaviour and 44.3% of the variance in intention across studies. This level of prediction of behaviour is slightly lower than that of previous meta-analytic reviews which have found between 27% (Armitage & Conner, 2001; Hagger et al., 2002) and 36% (Trafimow et al., 2002) of the variance in behaviour to be explained by intention and PBC.

🚨 A recent @pnas.org article raised serious concerns about LLM-based manipulation of online surveys.

Good news: We’re not helpless. In a new #OpenAccess article with @jkhoehne.bsky.social #bwolf, we show that LLM-driven bots can be detected using simple prompt injections.

Do you happen to work with data from the Integrated World Values/European Values Study? If so beware: there is a rather influential coding error in the variable on religious denomination (F025).
